多层螺旋CT在Peutz-Jeghers综合征诊断中的应用

目的：探讨多层螺旋CT在Peutz-Jeghers综合征诊断中的价值。方法：对6例临床怀疑Peutz-Jehers综合征患者进行多层螺旋CT扫描（平扫和动态强化扫描），对其轴位图像和重建的4-D、最大密度投影及仿真内窥镜图像进行观察分析，分别对各病例进行诊断。结果：6例患者中4例MSCT发现胃、小肠及结肠多发息肉，2例患者只发现空肠和回肠内多发息肉，MSCT诊断为Peutz-Jeghers综合征4例，另外2例诊断为家族性腺瘤性息肉病（FAP），MSCT诊断Peutz-Jeghers综合征的敏感性为100％，特异性为66．67％。结论：MSCT对Peutz-Jeghers综合征诊断准确性高，具有独特的优越性。

The application of multi-slice CT in diagnosis of Peutz-Jeghers syndrome

Objective:To study the diagnostic value of P-J syndrome using MSCT.Methods:6 patients with histologically and endoscopically proven P-J syndrome underwent multi-slice CT scans in prone position,with drug-induced hypotonia and airfilling colon,5% Ultravist filling stomach and small intesine.Two radiologists analyzed all imagings of the 6 patients,including: all axial imagings and all reconstructed imagings,such as volume rendering,CTVE,SSD and so on.Then they diagnosed.Results:All of 4 patients MSCT detected polyp in stomach,small intestine and colon.2 patients were detected polyp only in jejunum and ileum.The sensitivity of diagnosis P-J syndrome is 100% and speciality is 66.67%.The accuracy of MSCT is more high than others.Conclusion:MSCT is recommended for the diagnosis of P-J syndrome.
